Problems solved by technology

However, if they are placed too close together, the problem is that the opposing member 90 interferes with the process cartridge 86 when opening and closing the opening / closing portion 80
In a structure in which the process cartridges are arranged in vertical rows, it is important to keep the height of the image forming device 81 low, so that this problem becomes particularly serious.

Embodiment Construction

[0022] An embodiment of the present invention is described below. Such as figure 1 and figure 2 As shown, the printer 1 relating to the embodiment of the present invention is a full-color printer. It should be noted that, figure 1 The right side in corresponds to the front side of the device, while the figure 1 The left side in corresponds to the rear side of the device. In the printer main body 1M constituting the printer 1, there are provided four process cartridges 3, 4, 5, 6 arranged substantially vertically in a vertical row, and a transfer belt 7 arranged along these process cartridges 3, 4, 5, 6 . The transfer belt 7 is opened so that the process cartridges 3, 4, 5, 6 can be installed in and removed from this open space in a substantially horizontal direction. Photosensitive drums (image carriers) 11, 12, 13, 14 are provided at the process cartridges 3, 4, 5, 6, respectively.

[0023] The printer 1 has a ROS (Raster Output Scanner) 8 for image exposure at the re...

Abstract

There is provided an image forming device which has an opening / closing portion rotatably mounted to a device main body, and at which plural cartridges accommodated in the device main body can be exposed due to the opening / closing portion being rotated. In the image forming device, a portion of an outer peripheral surface of a belt, which is provided at the opening / closing portion, is positioned at a cartridge side of the opening / closing portion. An opposing member is provided at the opening / closing portion so as to oppose the portion of the outer peripheral surface of the belt. A guide portion, which guides the opposing member such that the opposing member can slide with respect to the device main body, is provided at the device main body.

Description

technical field [0001] The present invention relates to an image forming apparatus having an opening / closing portion rotatably mounted on an apparatus main body, and at which a plurality of cartridges accommodated in the apparatus main body can be exposed by rotation of the opening / closing portion . Background technique [0002] A color image forming apparatus generally has a plurality (for example, four) of process cartridges (for example, see Japanese Patent Application Laid-Open Nos. 2003-241466 and 2003-241620). In most cases, an opening / closing portion is mounted on the apparatus main body so that the plurality of process cartridges can be exposed for maintenance and the like. An example of a conventional imaging device will be described below with reference to the accompanying drawings. [0003] As shown in FIG. 12, a conventional imaging device 81 has an opening / closing portion 80 rotatably mounted on the device main body. By turning the opening / closing portion 80,...
